Configure a Choice Question as a Drop-Down List

Use the built-in Choice question type and change its format to a Drop-down to ensure markers select exact student names.

By default, choice questions in Microsoft Forms display as radio buttons. Changing this to a drop-down list is ideal when you have a large number of options, such as a full roster of student names or ID numbers. This method eliminates spelling errors and invalid formats entirely because the user cannot type custom text.

1
Add a Choice Question

Open your form in Microsoft Forms and click 'Add new', then select 'Choice' as the question type.

2
Enter the Options

Input the approved student names or exact ID numbers into the choice fields.

3
Enable Drop-down Format

Click the ellipsis (three dots) menu located at the bottom right corner of the question card and select 'Drop-down' from the menu.

Validation Limitation: Microsoft Forms does not currently support advanced custom alphanumeric input validation for text fields. If strict custom ID formatting is required, you must rely on pre-filled drop-down lists or use alternative form workflow solutions.

Frequently Asked Questions

Can I set up a custom alphanumeric input validation rule in Microsoft Forms?

No, Microsoft Forms currently only supports basic number validation (such as greater than, less than, or between). It does not natively support custom regular expressions or specific alphanumeric format validation.

How do I prevent markers from misspelling names on a form?

The most effective way to prevent spelling errors is to use a Drop-down list. By pre-filling the exact names or ID numbers as choices, markers are forced to select a valid option instead of typing it manually.

How do I export my form data to check for invalid entries?

Navigate to the 'Responses' tab in your Microsoft Form and click 'Open in Excel'. You can then open this file in spreadsheet software like WPS Spreadsheet to filter out or highlight invalid ID entries.
